Slowing Down With Some Fishing
What good would a festival be without a chance to relax and enjoy a hobby? Even fictional characters need hobbies, after all, and the hobby available to players in LOTRO is fishing. As such, the summer festival has a specific fishing quest to partake in if you wish, beginning with Neddie Grub, the quartermaster by the bridge in Bywater.
The quest that begins the festival fishing is to stock the pond next to him with fish that are representative of all the races of Middle Earth, so this quest will have you traveling a bit. First you'll need to fish inside Thorin's Hall for 3 Amberjack, then you'll head to the shores of Celondim for 3 Luillim, and finally, you'll head to Bree, to the pond south of Bree-town itself for 3 Drum. Once you've collected these 9 fish, you can return to Neddie Grub for 2 festival tokens.
Completing this first quest will open up the primary festival fishing quests. One will start with him, and each of the locations you collected fish from earlier will have one more, all starting with the fishing "Quartermaster" NPC at that location. These quests are timed quests wherein you catch as many fish as you can in the time allowed. The fish you catch can be bartered with the Quartermasters for tokens and other festival items, and each location also has one specific "Rare Fish" that's worth more to barter.
You can also earn a "Rare Fish" title for your character by collecting 10 of each of these fish. Since Bywater is full of the fish you presumably stocked it with in the first quest, the fish you catch here are all fish that can be bartered, unlike the other locations where you will still catch plenty of useless weeds and things, making Bywater by far the location that will net you the best rewards. As such, its time limit is half that of the other fishing locations. The timed fishing quests are each repeatable once daily, and each lasts for 20 minutes, except Bywater's quest, which lasts for 10.
